"If Grand Theft Auto IV is anything like the previous iterations, it will offer a robust single-player experience, the kind that can last several hundred hours. That always worked well in the past, but Rockstar decided that wasn't enough this time around and added a sizable multiplayer component. Here's the challenge for Rockstar: create a multiplayer experience good enough to convince players to leave the single-player campaign for a little while. That's a tall task. After spending a day checking out four of the MP modes, Ign are pretty certain Rockstar's succeeded."
